The M8 Greyhound is a wheeled armored car used primarily by the United States during World War II. Designed for reconnaissance, it features a 37mm gun and a crew of four. Its mobility and speed made it effective for scouting missions and light combat. The vehicle was built on a 4x4 chassis, allowing it to navigate various terrains. The M8 Greyhound was also used by several allied nations and remained in service for many years after the war, influencing the design of future armored vehicles like the LAV-25 and M1117 Guardian.
